Two stores, one company, almost the same starting price
The fact that separates the first two stores on this list is ownership: FUN and HalloweenCostumes both trade under the legal entity FUN.com, Inc., and both were founded in 1992 with headquarters in the United States. That shared back end explains why their costume ranges look so similar, and why the Halloween and fancy dress costumes ranking places them close together.
Entry prices differ only slightly. Costumes and accessories at FUN start at $4.99, while the range at HalloweenCostumes starts at $5.99. Both are single-item entry points rather than a full outfit, so use them to compare shelf pricing and not to budget a complete costume.
For a buyer outside the US, the shipping lists matter more than the price gap. FUN ships to the United States, the United Kingdom and Australia. HalloweenCostumes ships to 5 countries including the United States, Canada and the United Kingdom. Toynk ships to the United States only, so for anyone outside the US it is a display shelf rather than a place to buy from. Check the market list before you fall for a lower price.
Price: read the entry point, then read the range
Every price on this list is a starting price for the cheapest listing in a category, not a typical spend. Toynk's lowest collectible listing begins at $6.99, but that store carries action figures, vinyl figures, chibi figures and more rather than clothing, so it competes as a prop and accessory source instead of a costume seller.
Rubie's has no starting price in the same form here, which is itself a signal. Its range is listed as halloween costumes, kids costumes, plus size costumes and more, a tight Halloween-focused set covering adults, kids, plus-size, wigs and accessories rather than a fandom catalogue. The store was founded in 1951 and trades as Rubies II LLC in the United States.
The practical comparison is between breadth and focus. A fandom superstore lets you build a whole look, costume plus wig plus shoes plus props, in one basket. A specialist sells fewer lines and tends to make sizing and simple Halloween choices easier. Read the FUN review and the HalloweenCostumes review side by side before you decide which basket suits your list.
Range and sizing: superstore against specialist
FUN lists cosplay costumes, anime costumes, game costumes and more, which is the broadest costume type coverage of the stores here, and it carries the franchise mix anime, video games, Marvel and more. HalloweenCostumes lists the same costume type coverage and the same franchise set, so the choice between those two comes down to price, shipping markets and stock, not to category breadth.
Note the plus-size and kids lines in both lists. A franchise range without size coverage only helps if the character you want comes in your size, so check the size range on the product page before you commit to a long delivery window. Rubie's is worth a look here even without a franchise list attached, because halloween costumes, kids costumes, plus size costumes and more puts kids and plus-size costumes at the centre rather than the edge.
If your shortlist runs past these four, the Dress Up America review covers another costume-first option, while Uwowo, Cosplaysky and Amiclubwear lean on cosplay rather than Halloween dressing. Abracadabra NYC sits in the same cosplay-adjacent group. Match the store to the character, then match the character to your size.
Returns and support: the reliability check
Return windows are the clearest quality signal for a costume bought weeks ahead of a party. FUN allows 30 days and HalloweenCostumes also allows 30 days. Across the stores in this comparison, return windows run from 0 to 30 days, so both of those sit at the generous end of what buyers see.
Support reach is close between the two. FUN offers email, chat, phone and more and HalloweenCostumes offers phone, chat, help centre and more, so either gives you a phone line, live chat, email and a help centre. That combination matters most for the fiddly problems: a costume that fits badly, a missing accessory, a late parcel. Rubie's offers email, help centre and phone, with phone, email and a help centre but no live chat option listed, so plan for a slower exchange if a size needs sorting.
A loyalty scheme and preorder access are both listed for FUN, and both are listed for HalloweenCostumes as well, so neither gains an edge on either point. Check the Toynk review and the Rubie's review for the same three checks on the other two stores: return window, support channels and where they actually ship.
Which store fits which buyer
Buy from FUN if you are outfitting a whole group from one fandom and want costumes, wigs, shoes and props in a single order, and you are shipping within the United States, the United Kingdom and Australia.
Buy from HalloweenCostumes for the same fandom depth with a slightly lower starting price of $5.99 and a wider set of markets at 5 countries including the United States, Canada and the United Kingdom.
Buy from Rubie's when Halloween is the only occasion, when kids or plus-size fit is the deciding factor, or when you would rather deal with a costume specialist than a fandom generalist.
Use Toynk for props, figures and trading cards as additions to a costume bought elsewhere, and only if the United States covers you. Check the Halloween and fancy dress costumes rankings again once you know which of those four profiles matches your order.
